When it comes to fast-food dairy desserts, I'll take a DQ Blizzard over a McDonald's McFlurry or a Wendy's Frosty any day of the week. And, if the Blizzard fan club is any sign of things, I'm not alone. This year the Blizzard celebrates its 25th birthday and as part of Blizzard Customer Appreciation Week (April 19 to 25) participating Dairy Queens are offering a buy one any-size Blizzard and get a second one for a quarter. Are you able to get your Blizzard fix where you live? What's your favorite flavor?
